IMPROVEMENT IN FURNACES POR BOILING- AND PUDDLING- IRON.

The Schedule referred to in these Letters Patent and making pazt of the same To all whom it may concern Be it known that I, Janus WESTERMAN, of Sharon, in the county of Mercer and State of Pennsylvania, have invented anew and useful Improvement in Furnace for Boiling or Paddling Iron; and I do hereby declare that the thllowiug is a full, clear, and

exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawingforming part of this specification.

This invention relates to a. new and useful improvement in furnaces for boiling or paddling in and manufacture of wrought iron, whereby the bosh is more perfectly protected from injury by heat than in ordinary boiling furnaces, and whereby the waste heat is utilized; and

It consists in a partition in the \vater-bosh or chill around the hearth of the furnace, by means of which a return circulation of water is produced in the bush I and It also consists in a neck or flue in combination with the furnace, by means of which the surplus heat is utilized, as will be hereinafter more fully described.

In the accompanying drawingl 'igure 1 represents a top or plan view of the furnace with the cover removed, showing the bosh and,

the neck D into the firebox of the boiler, as seen in the drawing.

G is a partition'iu the water-bosh B. This partition connects with the bosh at one end, as seen-at H, dividing the bush into two parts or tbrming two separate channels, I and J, through which the water circulates, the currpnts moving in opposite directions.

The water passes from the boiler into the channel I, through tliepipe. E, and'moves around the end of the partition and mto the channel J, as indicated by the arrow, and back into the boiler through the pipe It. Thus a constant circulation through the bosh will be maintained.

The boiler 1 may be simply a reservoir of water. In passing through the bosh more or less of it will be converted into steam and be discharged through the upper pipe while the circulation will be forced by the specific gravity of the-water.

By means of the neck or discharge-flue D of the furnace all the surplus heat may be utilized for generating steam or other purposes.

In the use of any improvement I- do not confine myself to either a boilingora puddlinp furnace, although the furnaces are similar and may be identical in their form and general construction. lcousiderthe improvement in the bosh of much more importance in the former, as a m'uchjhighcr temperpture is'producedin boiling than in simply puddling iron.

Having thus described my invention,

I .claim as new, and desire to secure by Letters Patent The partition G. in the water-bosh of an iron-boiling or puddling furuac, substantially as and for the purposes herein shown and described.

'2. In combination with the water-bosh B and the boiler I the neck or fine D, substantially as and for the purposes described.
